Answer:

They biked for 1 hour and 38 minutes

Step-by-step explanation:

Here, we want to know the length of the biking time

Mathematically, from the time given;

if they had ended the biking by 2:47

They would have biked for 2 hours

But, as it can be seen, the biking stopped at 2:25 and that is (57-25 = 22 minutes earlier)

So, the length of their biking time would be;

1 hour and (60-22) minutes

and that is 1 hour 38 minutes
